Water cooler requirements

[jakeru]

Great data point, Tony - thanks! (Should come in handy if I ever should decide to go watercooled.)

My homebrew TIG cooler moves a lot of water at 40 PSI, I'd guess 2 quarts a minute but I can't remember exactly. I would think that the type and diameter of cables (and particular model of torch) would make more differance than the length of the cables. I have only tested my DIY water cooler with the stock torch that came with the 250EX. I should be getting a CK-200 watercooled torch with 25' superflex cables on Tuesday, so I could perform a delivery rate test using that setup if you'd like.

the water line pressure don't mean a thing its the volume of water being pumped threw the torch more water cooler torch . my pressure is like only 8 to 10 psi but water volume from my water line is a little under 2 quarts per min way over min specs . pic came out to small it say's min 1 quart per min volume for water flow. as for coolant lol i use flywheel grinding coolant and 5 gallons of distilled water . the coolant i 30 to 1 ratio mix that like 22 oz of the flywheel grinding lube it has a alga and chemicals to keep water from going rancid and pump lube . its over 2 years old and still looks like the day i put the water and coolant additive in .
